This is a fork of https://github.com/stevelittlefish/auto_midi_connect modified to use with desktop systems, consoles, and handheld devices running firmware utilizing Emulation Station such as 351ELEC, ArkOS, TheRA.

Tested with RG351v.

Scripts have been modified to place in a "ports" directory and run directly from the device.

Scripts could aslo could also work with a RetroPie installation.
